#### Operation

ここでの「オペレーション」とは、HTTPの「メソッド」の1つを指します。

以下のようなものの1つ:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...さらによりエキゾチックなもの:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

HTTPプロトコルでは、これらの「メソッド」の1つ（または複数）を使用して各パスにアクセスできます。

---

APIを構築するときは、通常、これらの特定のHTTPメソッドを使用して特定のアクションを実行します。

通常は次を使用します:

* `POST`: データの作成
* `GET`: データの読み取り
* `PUT`: データの更新

                        this.sizeExpiration = currentTime + cacheTimeout;
                        log.trace("Retrieved size info in additional query: {}", this.size);
                    }
                } catch (CIFSException e) {
                    // Size query failed, but we have basic info - continue
                    log.trace("Size query failed, continuing with basic info", e);
                }
            }

        Exception exception = new Exception() {
            @Override
            public void printStackTrace(java.io.PrintWriter writer) {
                // Simulate a normal stack trace output
                writer.println("Special test exception");
                writer.flush();
            }
        };

        monitorTarget.appendException(buf, exception);

Dennoch können wir das zu erwartende Schema für den Requestbody deklarieren.

### Benutzerdefinierter OpenAPI-Content-Type

Mit demselben Trick könnten Sie ein Pydantic-Modell verwenden, um das JSON-Schema zu definieren, das dann im benutzerdefinierten Abschnitt des OpenAPI-Schemas für die *Pfadoperation* enthalten ist.

        // Verify
        assertNotNull(deserialized);
        assertNull(deserialized.getMessage());
        assertNull(deserialized.getCause());
    }

    public void test_stackTrace() {
        // Test that stack trace is properly maintained
        DictionaryExpiredException exception = new DictionaryExpiredException();
        StackTraceElement[] stackTrace = exception.getStackTrace();

        assertNotNull(stackTrace);

        // Both instances should be of the same class
        assertEquals(exception1.getClass(), exception2.getClass());
    }

    public void test_stackTrace() {
        // Test that the exception has a proper stack trace
        FessUserNotFoundException exception = new FessUserNotFoundException("testuser");

        StackTraceElement[] stackTrace = exception.getStackTrace();
        assertNotNull(stackTrace);

                }
                // one extra acquire to keep this open till the stream is released
                return this.handle.acquire();
            }

        }
        log.trace("Pipe already open");
        return this.handle.acquire();
    }

    /**
     * {@inheritDoc}
     *
     * @see jcifs.SmbPipeHandle#getInput()
     */
    @Override

        String stackTrace = sw.toString();

        String fullMessage = message + "\n" + "Exception: "
                + e.getClass().getName() + "\n" + "Message: "
                + e.getMessage() + "\n" + "Stack trace:\n"
                + stackTrace;

        processingEnv.getMessager().printMessage(Diagnostic.Kind.ERROR, fullMessage);
    }

                                            <la:option value="INFO">INFO</la:option>
                                            <la:option value="DEBUG">DEBUG</la:option>
                                            <la:option value="TRACE">TRACE</la:option>
                                            <la:option value="ALL">ALL</la:option>
                                        </la:select>
                                    </div>

"Operation" here refers to one of the HTTP "methods".

One of:

* `POST`
* `GET`
* `PUT`
* `DELETE`

...and the more exotic ones:

* `OPTIONS`
* `HEAD`
* `PATCH`
* `TRACE`

In the HTTP protocol, you can communicate to each path using one (or more) of these "methods".

When building APIs, you normally use these specific HTTP methods to perform a specific action.
